Chemical contaminants were assessed in Sydney Harbour, Nova Scotia during pre-remediation (baseline) and 3 years of remediation of a former coking and steel facility after nearly a century of operation and historical pollution into the Sydney Tar Ponds (STP). Concentrations of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls, metals, and inorganic parameters measured in sediments and total suspended solids in seawater indicate that the overall spatial distribution pattern of… Expand
Environmental recovery in Sydney Harbour, Nova Scotia: evidence of natural and anthropogenic sediment capping.
TLDR
Concentrations of PAHs; PCBs; and lead measured in surface sediments indicate overall spatial distribution patterns of historical contaminants remains unchanged, although at much lower concentrations than previously reported due to natural sediment recovery. Expand
Legacy contaminant bioaccumulation in rock crabs in Sydney Harbour during remediation of the Sydney Tar Ponds, Nova Scotia, Canada.
TLDR
Current contaminant burdens measured in crabs were much lower than previously reported in other studies of crabs and lobster in industrial harbours in eastern Canada, due in part to natural recovery of SH sediments. Expand
Ecological Risk Assessment of Sediments in Sydney Harbour, Nova Scotia, Canada
Contamination within sediments of Sydney Harbour (once a major industrial port) were evaluated using a multiple lines-of-evidence (LOE) ecological risk assessment (ERA) approach prior to divestitureExpand
Monitoring water quality in Sydney Harbour using blue mussels during remediation of the Sydney Tar Ponds, Nova Scotia, Canada
TLDR
The lack of detection of most individual PAHs and PCBs, plus relatively low bio-accumulation of metals observed during baseline and remediation attest to the effectiveness of using mussels as monitoring tools for environmental quality. Expand
Baseline characterization of sediments and marine biota near industrial effluent discharge in Northumberland Strait, Nova Scotia, Canada.
TLDR
Results indicated limited contamination in sediments and biota, posing low risk to marine biota when compared to Canadian Council of Ministers of the Environment sediment quality guidelines and Canadian Food Inspection Agency tissue guidelines. Expand
Spatiotemporal characterization of metals in small craft harbour sediments in Nova Scotia, Canada.
TLDR
Despite wide temporal coverage (16 years), large variation in sediment concentrations across SCHs were likely due to regular dredging activities preventing long-term accumulation of contaminants, suggesting limited ecological impairment to marine biota. Expand
Spatiotemporal assessment (quarter century) of pulp mill metal(loid) contaminated sediment to inform remediation decisions
TLDR
To help return Boat Harbour to a tidal estuary, more detailed sampling is required to better characterize these sediments and to establish appropriate reference (background) concentrations to help develop cost-effective remediation approaches for this decades-old problem. Expand
Characterization and spatial distribution of organic-contaminated sediment derived from historical industrial effluents
TLDR
High sediment PCDD/F concentrations have persisted in Boat Harbour despite implementation of Pulp and Paper Mill Effluent Chlorinated Dioxins and Furans Regulations in 1992, and remediation of the entire sediment inventory is recommended. Expand
Blue mussels ( Mytilus edulis ) as bioindicators of stable water quality in Sydney Harbour during remediation of the Sydney Tar Ponds, Nova Scotia, Canada
Contaminants were measured in blue mussels ( Mytilus edulis ) in Sydney Harbour (SH) during remediation of the Sydney Tar Ponds (STPs) to assess the spatio-temporal distribution of polycyclicExpand
Forensic assessment of polycyclic aromatic hydrocarbons at the former Sydney Tar Ponds and surrounding environment using fingerprint techniques.
TLDR
PAH contamination of Sydney Harbour sediments and urban soils is largely unrelated to historic coking operations or recent remediation of the STPs site, but rather a legacy of extensive use of coal for a variety of activities. Expand

Natural rates of sediment containment of PAH, PCB and metal inventories in Sydney Harbour, Nova Scotia.
TLDR
Mean sediment concentrations of metal and organic contaminants in the upper 5 cm throughout most of the harbour are predicted to decline to levels below the effects range-medium (above which organisms are very likely to be negatively affected by the presence of a contaminant) by 2030. Expand

Ecotoxicity assessment of natural attenuation effects at a historical dumping site in the western Baltic Sea.
TLDR
Recent sediments of the historical dump site are still significantly enriched in heavy metals and PAHs, though uptake of contaminants in mussels was found to deviate only slightly from that of a non-contaminated reference station due to a gradual dilution and decrease in bioavailability of the contaminants.

TLDR
The overall approach for effective implementation of MNR for contaminated sediment sites is discussed, including documentation of source control, evidence of contaminant burial, and several lines of evidence that may be used to demonstrate natural recovery processes. Expand

TLDR
Pollutant hydrocarbon concentrations have increase 100-fold since about 1900, and contamination of sediments by the metals Cu, Zn, Pb, and Hg has also increased from 1890 to 1970, with maximum levels among the highest reported from other urban and industrialized coastal marine areas in the world.
